Free online knowledge for the paving industry. Asphalt concrete base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). In addition to site paving benefits, ACB can be advantageous because it can provide:
Crushed rock or gravel of approved grading up to a maximum size of 14 mm. The excavated material may provide a suitable pipe underlay if it is free from rock or hard matter and broken up so that it contains no soil lumps having any dimension greater than 75 mm which would prevent adequate compaction of the bedding.
The feed size will depend on factors such as the closed side setting, eccentric throw, and head diameter. Exceeding the max feed size will lead to premature crusher failure. Use the minimum CSS and throw to determine the largest feed material allowable. Anything over this size could cause rotor stalling and damage to internal parts.
